The proof is almost identical to that of [1]}. We only need the analogues of the differential theorem of measures and Hardy-Littlewood maximal inequality in terms of \(\gamma \) -Morse sets rather than balls. The former can be found in [2]}. The later is an easy consequence (see for example the proof of [3]}) of Besicovitch covering theorem for \(\gamma \) -Morse coverings, namely the Morse covering theorem [2]}.
